'Every single day this base is at war. These kids are not playing video games out of their mothers' basements'. The pilots sit in dimly lit, air-conditioned trailers, each staring at glowing video and data screens and toggling a joystick that controls an armed drone flying somewhere in the world.
In this experiment, you will measure the amount of energy available for use from three types of nuts, a plant product. This process of measuring the energy stored in food is known as calorimetry.
Energy as kilojoules. A kilojoule is a unit of measure of energy, in the same way that kilometres measure distance. Food energy can also be measured in terms of the nutritional or âlargeâ Calorie (Cal), which has the same energy value as 4.186 kilojoules (kJ).
